The details of Sessions' announcement are still unclear but some local law enforcement agencies say it will not change how they operate since they follow state law.

"We're not going to change how we police any of our communities, we don't segregate or differentiate between the communities that we serve," said Alameda County Sheriff Gregory Ahern.

The sheriff says there's conflict with state and federal law when it comes to immigration enforcement. If the feds decide to pull funding from local law enforcement agencies not in compliance, they could lose up to $1 million.

"What we wish is that there was one federal law that dealt with immigration that was a fair basis that the elected officials neglected to work on for about a decade," said Ahern.

At a time of unprecedented political turmoil, Jeff Sessions has come to California to further divide and polarize America. Jeff, these political stunts may be the norm in Washington, but they don’t work here. SAD!!!

Sacramento, even though I couldn’t get a flight back home tonight, I will be standing with you from here in Washington DC during Jeff Sessions' planned visit because we always stand together to defend, uplift and support our diverse immigrant community. pic.twitter.com/w6paSyE4SB
